"I was really getting pissed to see who's in the top 100,'' Gulbis said after squeaking out a three-set victory over Denys Molchanov. "There are some guys who I don't know who they are. Some guys, I'm sorry, with respect — they can't play tennis.

"I don't know how they got into the top 100. It's tough, but I think I'm much better than them and I just want to prove to myself by the rankings, also. It's a motivation.''
